It's time to burn it down

From Disctrict 9...It fires a bolt of energy lightning and vaporizes enemies...produces its own energy/ammo and has user I.D. tech. so that only the aliens could use it...since it's my pick I get to mod it to work for only ME. And if it can fry aliens and humans..should do zombies nicely.
